The castle was abandoned in 1760, when it was badly damaged by lightning. The remains of a turret of a tower, are still resting upside-down in the centre of the courtyard. In 1817, the water level fell and since then the castle is connected to the mainland, resting on on a rocky peninsula at the northeastern end of Loch Awe.

Today, Kilchurn Castle is in the care of Historic Scotland and it is open for visits during the summer months.
